Strong Final State Interactions in gamma.gamma --> W+W-

Abstract

We study the effects of a possible strong final state interaction among longitudinal W's in gamma.gamma --> W+W-. The relevant partial wave amplitudes are modified by an Omnès function approximated by a Breit-Wigner form factor. We study the fractional cross section f_{00} = σ_{LL}/σ_{Total} with both W's longitudinally polarised, in the presence of a J = 2 resonance (M = 2.5 TeV, Width = 500 GeV) or a J = 0 resonance (M = 1 TeV, Width = 1 TeV), whose parameters are scaled up from the f_2 and σresonances in the ππsystem. We also examine the effects of final state interaction in the case of polarised photons (J_z = 0 or J_z = 2), and the impact on the Drell-Hearn-Gerasimov sum rule.
